IMPROVEMENT m CULTIVATORS.

Specificationforining part of Letters Patent No. 174,320, datedFebruary29, 1876 application filed r December 4, 1875. i

ments in Cultivators or Corn-Flows, of which the following is adescription, reference being- I had to the accompanying drawings:.

My invention consists, first, of the arrangement and combination ofparts whereby the arch of a corn plow or cultivator is supportedindependently by each plow; second, the construction and arrangement ofpartswhereby the plow-shovels can be adjusted to-any desired depth inthe ground; third, in the construction and arrangement of the draw-barswhereby the spindles of the wheels are in front and below the archedaxle.

Figure 1 represents a side elevation of my improved cultivator. Fig. 2is a plan view of the same, showing the arrangement of parts more fully.Fig. 3 is an enlarged plan view of the connections of the plow-beamswith the independent arch-supporting boxes. Fig. 4 is a side view ofFig. 3, showing the arrangement of parts for the adjustment of theplow-shovels in the ground. Fig. 5 represents a front and side view ofthe adjustable sled-runner or plowpoint support. Fig. 6 is a sectionalview of the independent arch-supporting boxes, showing the arrangementof the collar and top and bottom studs, that operate in slots formed inthe top and bottom halves of the supportingboxes. Fig. 7 shows thecollar on the arched axle. Fig. 8 represents a top view of the drawbarand wheel-spindle. Fig. 9 is an end view of Fig. 8. Fig. 10 shows twoside views of Fig. 8. Fig. 1.1 represents the manner of attaching thesled-runners or plow-point supports and fender to the plow-beams. Fig.12 is a side view of the fender andclamp.

A A represent the wheels of the cultivator, which are mounted on thespindles B that are secured to the projection B of the drawbar 0. (Shownmore fully in Figs. 8, 9, and 10.) hook, D, at the front end. The otherend is provided with two projecting flanges, (3 G which form jaws, thatfit overand under the flanged end pieces B of the arched axle B B and ispivoted thereto by the bolt 0 Theend piece B has flanges 0 0 above andbelow,

The draw-bar G is also formed with a so as to present a wide bearing onthe inside of the jaws Q 0 and the end of the arched shaft or axleisinserted in the piece B and secured therein by the pin 00. (Shown inFig. 3.)

In Figs. 1, 2, and s it will be seen that the spindle B is located belowand in front of the arched axle B B and is free to move in any directionon the pivot-bolt O, as indicated by :the dotted lines y y, Fig. 2, andallow the wheel A to follow the horse independent of the other wheel,with the draft below the arched axle BB which will allow the wheels topass over obstacles with little or no strain on the arched axle.

On the arched axle B B between the arch B and end pieces B are securedthe collars m, Fig. 7, with a stud, 'w above, and 10 below, Fig. 6. Overand under these collars w 10 and encircling the shaft'B, are the independent arch-supporting boxes R E, Figs. 2,

.3, and 6. Each of these boxes are perforated with a slot, to, above andbelow, through each of which the studs w and 242 project, the design ofwhich is to support the arch in a perpendicular position, and prevent itfrom turning down either in-front or rear.

The two halves of the independent arch-supporting boxes R R aresecuredtogether bybolts h h in the lugs g g in-front, and by the bolts01 at the rear. to. the attachments M N on the end of the plow-beams, soas to allow the plows P to be moved laterally either way, as indicatedby the dotted lines ff, Fig. 2.

The plow beams are curved downward at their rear ends, and are providedwith shovels P, attached in the ordinary manner. The front ends of thebeams E E are securely bolted to the sides of the gib-slide S. (Shownmore fully in Figs. 3 and 4.) The front end of the piece S is formedwith a gib, S, that fits on both sides of the upright slide N, and issecured at any desired height by the bolt 10 passing through the slot N,which will allow the plows'to be adjusted to any desired depth. At therear of the slide N, and cast on the top and bottom of the gib-piece S,are lugs or brace-guides T, that help support the beams against theslide N. On the front side of the slide N is cast the pivoted connectionM, that The bolt 01 acts as a pivot i is pivoted tothe independentrarchsuppotting boxe's RRtbyithe pivot-bolt d; before described.

The two plow-beams E E, on each side of the arch B are formed with theinner beam shorter than the outside beam, and the handle F is secured bythe.bolt .J and brace-Gr, as. shown in Fi'gSILandZ. "GW'theinsideOftheshort beams E, and attached thereto by the bolt J, is the washer V,'with:theesled-ru nner or plow-shovel-supporting arm K, pivoted-on thebolt, between the washer V and the fend er-clamp U. (Shown more fully in.Fi g. ,11.)

The sled runner orshovl support is shownl fully in Figs."1, 2, and 5,and is constructed with an arm, K, at the bottom of whichisthe. slide orrunner L.
